BACKGROUNDAND BRIEF SUMMARY OF THE INVENTION I The present invention relates generally to the siphoning art,,.and more particularly to a novel keg adapter valve and to apparatus-for and a method of installing.

said adapter valve inside a keg having a relatively small dispensing opening, as for example, a Peerless beer keg. Although the present invention has utility in dispensing otherliquids from other types of containers, it is especially useful with the aforementioned Peerless keg for admitting cleaning fluidsinto said keg and for dispensing beer therefrom, and it willbe so described.

As referredto in the aforementiened copending applications, for many years the prevailing draftsystem fordispensing beer from kegs required a wooden cork which sealed an opening in one end of the keg, which cork was removed by the bartender who then inserted into the opening an elongated tap rod assembly. which had a siphoning device associated therewith. Means,

were provided for injecting compressed air or carbon dioxide into the keg through the tap rod assembly, whereby the beer was driven outof the keg through the siphoning device to a spigot or the flow of beer from the keg. V 4

After all of theavailable beer had been withdrawn from the keg, the bartender'wouldthen remove the tap faucet which controlled rod assembly and siphoning device from the spent keg and repeat theprocess with a fullkeg. Inasmuch as the same tap rod assembly and siphoning device were used over and over again, it was necessary for the bartender to frequently clean the unit in an effort toremove old yeast deposits and bacteria so as to avoid contaminatingthe beer in the fresh barrel. I

Another problem with the aforementioned draft system was that the spent or empty kegs had an opening inthe end thereof from which the cork had been removed, which opening permitted all kinds of foreign matter and things to enter the keg. Consequently, the

cleaning of these kegs at the brewery prior to refilling was a laborious and costly process. i

Being familiar with the aforementioned problems, I invented various beer tapping assemblies which include a keg "adapter mounted int'he keg and including a spring-biased valve which remain closed to prevent the escape of beer until a tapper was engaged with the adapter and actuated to cause a probe to unseat the aforementioned valve and to permit the beer to flow' therefrom under pressure from asource or compressed air or carbondioxide which was connected to the tapper. i

Although these new forms of keg adapters and tappers constituted a considerable improvement overv the prior beer tapping devices, they were "not completely satisfactory, primarily because of the problems encountered with properly washing all of the various parts and passageways contained in the keg adapter, includingthe various coiled springs which maintained valves and parts in closed andin engaged positions; I

A further problem with existing equipment, was that it was often difficult for a woman bartender to'properly engage the tapper with the keg adapter, and subsequently actuate the probe to tap the keg and release the beer. a

Realizing the limitations of prior tapping equipment and of my own developments, I then invented a novel tapper usable with various types of keg adapter units,

and a novel keg adapter valve which employs sets of permanent magnets for actuating valve members which are associated with the liquid and gas passageways and by means of which gas under pressure is admitted into the keg and-beer is-withdrawn therefrom. The tapper and various forms of keg adapter valves are shown and described in the aforementioned copending-appli'cw Persons familiar with the beer dispensing art know there are two main types of beer kegs in use at-the present time, the Golden Gate keg which hasa dispens ing opening approximately 1% inches indiameter, and the Peerless keg whichhas a like opening approximately three-fourths of an inch in diameter. My aforementioned copending application Ser. No., 385,358, filed Aug. 3, 1973, shows and describes a keg adapter valve for use'with the Golden Gate keg and in which the keg adapter is easily mounted in the keg by inserting it through the 1% inch opening from the outside of the keg. L i I Because of the size of a valve"adapter body' required to receive the aforementioned permanent magnets for actuating the gasand liquid valves, ='s'uch' akej'gvalve adapter could not be-"rnade of asize-to be inserted through the three-fourths of an inch dispensing opening Accordingly, it is an object of the present invention to provide a novel keg adapter valve containing magnetic valve actuators, which can be used with a rela-' tively small opening in the wall of a keg or the likeias three-quarter inch opening. I Another object is to provide such a tion as the valve body of my keg adapter valve which is usedwith the Golden'Gate keg.

A further object is to provide a keg adapter valve for the Peerless beer keg, which is usable with my tapper unit now used with the keg adapter valve for the Golden" Gate" keg. l

Yet another object is to provide apparatus for and a method of mounting the aforementioned valve body internally of the Peerless 'keg. More particularly, it is an object to provide apparatus and a-method for inserting the valve body through the bunghole in the side wall of a Peerless keg and for guiding it to and maintaining it in engagement with the end wall which contains the small'dispensing opening while it is being fastened in position.

I have discovered that the foregoing objects and advantagesareachieved with a keg adapter valve assembly which includes a valve member with a central opening-and a separate gas passageway, adapted to be keg adapter valve which has a valve body of the sarneg'eneral configure:

the interior of the keg in which the assembly is mounted.

The valve member is guided through the bunghole of the keg to a position inside the keg in alignment with the keg dispensing opening, where it is held in position while the tapper connector member is fastened thereto from outside of the keg, and the elongated tubular member containing the liquid passageway isthen inserted through the tapper connector member andthe valve member, to complete the assembly.

DESCRIPTION OF THE PREFERRED,

EMBODIMENT Referring to the drawings more particularly by reference numerals, and particularly to FIG. 1, the number 14 indicates generally a keg adapter valve assembly constructed in accordance with the teachings of the present invention, shown installed in the dispensing opening ofa Peerless beer keg 16 which includes an end wall 18 containing a cavity having a bottom wall portion 20 supporting a tubular portion 22 which defines a passageway 24 and which terminates at the top Q in an annular, laterally extending flange 26.

The keg adapter valve assembly comprises an external tapper connector member 28, an internal valve member 30 fastened to said connector, and a liquid passageway member 32 which is received in the tapper connector member and the valve member.

First considering the tapper connector member 28 (FIGS. 1-4), it is preferably made of stainless steel and is generally cylindrical in shape with an upper cylindrical cavity 34 having two diametrically opposed slots 36 at the upper edge thereof, each of which is in communication with a circumferentially extending tapered groove 38. These slots and grooves receive depending leg members (not shown) on the tapper unit which is shown and described in my copending application Ser.

' No. 385,358,'filed Aug. 3, 1973, whereby said tapper can be connected to the tapper connector member 28. At the bottom of the cavity 34 is a horizontal wall 40 which contains four circumferentially spaced gas ports 42 which lead into radially extending grooves 44. .As 3

shown in FIG. 3, arcuate ridges 46 are provided on the underside of the wall 40 between said gas ports. An annular flange portion 48 depends from the outer periphery of the horizontal wall portion 40 to provide a bot-. tom cavity, and an annular sealing washer 50 is positioned in said bottom cavity in engagement with the flange portion 26.

The bottom wall 40 also contains an opening at the center thereof and a tubular portion 52 depends from the wall 40 in registry with said opening, the bottom end of said tubular portion containing external threads 54. As shown in FIG. 1, the outer surface of the tubular portion 52 is spaced inwardly of the inner surface of the tubular portion 22 to provide a gas passageway 55 therebetween which. is in communication with the gas ports 42 and connecting grooves 44.

Referring next to the internal valve member 30 (FIGS. 1, 5 and 6), it is preferably made from a plastic material such as polyterephthalate (Eastman Chemical Products PTMP-6 PRO), which can withstand caustic cleaning materials, and includes an upper cylindrical hub portion 56 with an upper wall 58. The wall 58 sup ports a peripheral, vertically extending flange 60 which contains an annular groove 62 for receiving an O-ring 64 which is in sealing engagement with the bottom wall portion 20 of the keg cavity (FIG. 1). The flange 60 and the upper surface of the wall 58 define a shallow cavity 66 which is in communication with the aforementioned gas passageway 55.

A central. opening 68 extends through the wall 58, the upper portion of which is relieved to receive an internally threaded metal bushing 70 which engages the threaded bottom portion 54 of the tapper connector member. An annular groove '72 is contained in the opening 68 at the bottom end of the bushing 70, for a purpose to appear.

Depending from the cylindrical hub portion are two diametrically opposed leg portions 74 (FIG. 5), each of which contains a central gas passageway 76 which extends through-thehub portion 56and which has the upper end thereof in communication with the shallow cavity 66, which, as previously mentioned, isin communication with the gas passageway 55.

A'gas valve seat 78 is contained in eaclig way adjacent theupper end tliereofifo'r'eiiga'genient by a gas valve member 80 which'c'ontai i vertical-extendingridges and grooves to'pi vide forthe flow of'gas around it when it is in' the'open position.

Received in each gas passageway is an elongated cylindrical permanent magnet 82 which functions as a upper portion ofthe gas passageway-when the gas valve member 80 is spaced from the valve 78in the'open position.

Associatedwith each magnet valve actuator 82 is a set of two/elongated cylindricalpermanentmagnets 88 whichare embedded in passageways molded'in the leg portionsy-the ends-of said passageways being enclosed by =pltigs90 which are cemented in position. These stationary magnets 88 are substantially parallel with the movable magnet 82-and are spaced anequal-distance therefromeAlso, the'ends of the permanent magnets are offset. as shown 'in FIG. 6, with the, upper ends of Both stationary magnets 88 being abovethe upper end ofithe movable magnet 82 when the gasvalve member 80 is in the closed position. The'upper ends of the stationaryzmag nets 88 are of the same polarity and are opposite in polarity to the polarity of the upper end of the movable magnet 82, whereby the latter is urged upwai'dly'toward the upper ends of the'stationary magnets and-toward the closedvalve position. Referring next to-the-liquid passageway member 32 (FlGil' l), it is preferably made of-stainlessste'el and'includes a tubular body portion 92 which provides a liquid passageway, and which'has a tubular bayonet'fitting 9 4 fastened to'the upper end thereof to provide an inrather liquid valve seat 96. The upper end of the fitting 94 has an external annular groovewhich receives an i-ring 97 A spring retaining member 99 is received in anfexte rnal groove in the upper part of the tubular body portionffor apurpose' to appear.

"Adiiaceiit' thelower end of the body port'ion is a relatively large' exter'rial groovewhich receives'an O-ring 98 of a relatively large thickness, and below it is anothei' external groove which receives a smaller O-ring loat e latterp 'rovidihg a flu'id seal between the tubular portion and theinn er wall of th'e'central openiri g'68 of the iialve member. i g Fastened in the bottom end of the tubular body por- 6 friction, the upper endof 's'aid magnet supporting a liquid valve member ll'2-"forengagement with the liquid valve seat 96'. As shown in FIG. '1, the tubular extension is smaller in diameter than the tubular body portion 92 to provide an annular spaced therebetween, which functions as theliquid'passa 'geway by means of which beer is dispensed from the keg and washing fluid enters the keg during the cleaning operation.

The polarity at the upper end of the movable inagnet actuator is opposite to the polarity of the upper e'ndsof the twosetsof stationary magnets 88,'where'by the upper endvof the magnet actuator 110 is repelled" to yieldably biasithe liquid valve member 112 toward the closed position. The axis of the movable magnet 1 10* is substantially parallel with the axes of the stationarymagnets 88, and, as indicated in FIG. 5,-the fo'ur stationary magnets 88 are equi-distant from the magnet actuator 110, ;as well as1being {equidistant from the magnet actuators 82 for the two gas .valve members 80. 1 The operation of athekeg adaptervalve 14 forthe introduction oficleaning fluid-into ath'elkeg and theoperation thereof for the dispensing ofbeer inassociation with my novel tappe r memberv is similar to the operation ofthe adapter valveshown and described in my copendirigapplication, Ser. No, 385,358, filed Aug.u3, 1973, and, accordingly, that description is incorporated herein by reference.

As referred to above, the size of the actuator magnets and thestationary magnets associated therewithmake it impractical to install the valvernember 3 0 through the threequarter inch dispensing. passageway of; a Peerless? keg. Accordingly, I have invented novel apparatus ifor, and a method of installiln gi the valve m ember through the bunghole. of a .Plee rlessnkeg, as illusra edjihhlos. 7 through l l The installation apparatus includes a ,le rigth of fleiri ble lead cable 114 whieh has ahandle;1 l6' at the Outfit end thereof and a slotted receiver member 118 of a quick connect-and-disconnect assembly at the inner M,

'The bayonet portion 1 2 0 of :the ismounted on end of a rigid tubular upper am 132, the 'th'e'r endof which is pivotall'y connected at 12416 as rnilar t kit a m fia The ".quick connect-and-dis'connect assembly U can take different forms, the primary criteria being thatth'e bayonet portion 120 is small enough to pass through the central opening 68 of the valve member 30 (FIG. l) and through the tubular portion 52 of the tapper connector member 28 (FIG. 4).

Fastened to the lower end of the lower arm 126 is a rectangular support plate 128 which is of a width to pass between the space-apart depending leg portions 74 (FIG. 5) of the valve member 30, but which has a length greater than the space between said leg'portions. A flexibletrailing cable'130 has one end thereof fastenedto the support plate 128 and'the other end contains a disc 132 which is slightly larger than the bunghole ofthe keg. 3

To'install the keg adapter valve assembly 14 in the dispensing open'in'g of the Peerless keg 16, the slotted receiver portion 118 of the connector and the lead cable 114 are inserted thro'iugh' the tubular portion 22 o f the keg dispenser opening (FIG. 7) and'into the keg; lo withdraw the slotted receiver portion 118 through the bungholefa wire hook 134 isinserted through the bunghole 136 to engage the lead cable 114 and thereby 1 pulled through the bunghole 136 and through the tubular portion 22 until the O-ring 64 (FIG; 1) engages the bottom wall portion 20 of the keg cavity (FIG. 8). In

this position, the disc 132 is received in the bunghole 136 to prevent the trailing cable 130 from passing completely into the interior of the keg.

As shownin-FIG. 8, the slotted receiver 118 of the connector is disengaged from the bayonet portion 120 and the tapper connector member 128 slipped over the bayonet portion "120, the upper arm 122 and the lower arm 126, and until the external threads 54 (FIG. 4) begin to engage the internal threads of the bushing 70.

The upper arm 122 is then turned to a right-angle position as shown in FIG. 9, and, while being maintained in that position, the tapper connector member 28 is threaded into engagement with the aforementioned bushing 70 until the washer 50 (FIG. 1) is held tightly between-the flange 26 and the wall of the connector member 28 opposite thereto, and the O-ring 64 is in fluid tight engagement with the wall portion 20.

The upper arm"12'2 is then moved to the vertical position and the two ar'ms pushed downwardly through the tubular portiori 52',"a'nd, at the same time, the operator pulls on the disc 132 to remove the trailing cable 130 and the arms 122 and 126 through the bunghole 136, as shown in FIG. 10. v

Referring to FIG. 1, the bottom end of the siphon tube 104 which has the liquid passageway member 32 mounted on the upper end thereof, is inserted downwardly through the tubular portion 52 of the tapper connector member 28, until the O-ring 98 is received in the annular groove 72. In this position, the spring retainer member 99 adjacent the upper end of the tubular member 92 engages the upper end of the tubular portion' SZ, thereby limiting any further dow'nward movement of the passageway member 32.

The keg adapter valve assembly 14 with the siphon tube 104 is thereby securely installed in the dispensing opening of the keg, as illustrated in FIG. 11. In this assembled position, with both the liquid valve member and the gas valve members being maintained in the closed position by the magnet actuators, the keg 16 can be filled through the bunghole 136 in the conventional manner, and the bunghole closed with a wooden bung 138.

Thus, it is apparent that there has been provided a novel keg adapter valve and apparatus for and method of installing the same in a Peerless keg, which fulfills all of the objects and advantages sought therefor.
